I found L&L an excellent company to deal with from start to finish. They are a professional company and the fitters are a credit to them, working hard , they are polite and very tidy . The office staff are equally as helpful and happy to help with any queries there may be. The product is well made and good quality. Although it may seem they are more expensive than other companies, the quality, professionalism and follow up service are well worth it for extra piece of mind . Thank you very much L&L .

I would highly recommend. L & L Installations Limited. We had 5 sets of windows replaced in our bungalow, one being very large. The customer service was brilliant from first contact. Clear pricing, no hard sell. They came when they said they would and it was finished when they said it would be. We are so pleased with the windows, and the young men who fitted them were a credit to the company. They were very polite and respectful and left everything so clean and tidy each day when they left. The communications from the office were clear and prompt too. Overall a 10/10 experience.

Quality of the product is outstanding, and we look forward to it serving us for many years to come. Thanks to all involved, we wouldn't go anywhere else.

Bedroom window installation

On 21/11/2024, L&L Installation fitted a new bedroom window in my home. From start to finish the service that I have received has been outstanding. After contacting L&L Installation are the beginning of September to initially come to my home to take the necessary measurements in order to provide me with a quotation, to arranging a convenient date for the window to be installed has been highly commendable. The level of efficiency, communication, professionalism and attention for detail has been most impressive. The window is of a very high standard, the work was carried in a very timely manner and I am very pleased with how the window looks overall, so much so that I will be looking to contact L&L Installation as I intend to have my other two bedroom windows replaced. I can highly recommend L&L Installation to anyone who is considering replacing any type of window, a new front door , patio door, or whatever to contact L&L first and I am confident that they won't be disappointed.

L and L have done several jobs for me over a space of 15 years; ie replacement windows and doors and the construction and glazing of a conservatory. During the 10 year guarantee period they have carried out minor repairs punctiliously. The latest maintenance job at above date was carried out out of guarantee at no charge. I highly recommend this company's workmanship, after sales service and ethos.

We are delighted we are with L&L’s aftercare support. Not only does L&L offer annual service checks, but their aftercare is second to none. Recently we noticed that one of our double glazed window panes had condensation inside the glass and had blown. We contacted L&L to arrange a repair, fully expecting to pay for this as our windows were around 10 years old and therefore out of warranty. L&L sent someone straight out to investigate, then arranged to replace the pane free of charge ‘because it was only just out of warranty’ How many other companies would do this? L&L weren’t the cheapest company who quoted for our windows, but were the only company to offer us the shape we wanted as an integral part of the window and not a bolt on. Looking back they were worth every penny. We couldn’t be happier with the service received, and wouldn’t hesitate to recommend L&L to others.

Having had 2 other companies try to fix our faulty doors with no success, your Service manager Phil came out and after an inspection diagnosed the problem and that they would be repairable. Phil returned in mid June and repositioned the doors and replaced all the screws with different screws. They have now been working perfectly for a couple of months and would like to say that Phil has done an excellent job.

Great to be able to visit a local business with a showroom. Everyone we've had contact with at L&L has been excellent - great communication and very professional. We ordered some Aluco aluminium French doors. The whole process has been faultless. The fitters took their time and have done a fantastic job. We are currently in the middle of a renovation and all the builders on site commented about how impressed they were with the standard of fitting. Would highly recommend L&L - they certainly deserve all the 5* reviews.

I have had several installations from L&L over the past 14 years including patio and bifold doors and they were all done to a high standard. This time it was the casement windows which needed replacing and it took me some time to decide on the interior colours. The sales advisors were very patient with me, supplying samples to take home to enable me to decide on colours and 'woodgrain' for the frames and cillboards. On the installation day the team worked so well together and they were all pleasant guys to have in my house. They got the job done quickly and well and minimised the mess by covering all of the adjacent furniture with clean dust sheets. They also tidied up extremely well before leaving. I can certainly recommend this company.

L and L come recommended and I had heard good reviews so even tho we had a few quotes and they were priced very well we went with them. James’s knowledge and experience about the products is second to none. We are in the middle of a renovation so def have them back to do the rest. Door ordered and we did have to wait but not a major problem given the pandemic we have been in. Lads arrived to fit it they were clean, tidy and very polite. Cleared all the mess and kept everything tidy. We are absolutely over the moon with the service provided, cost and installation process. Well done L & L incredible company with great customer service. I shall not hesitate to keep recommending them. Thanks everyone!

I chose L&L because I wanted to support a local company and I could see that they had secured great reviews regarding their service and quality of doors. From the first survey, to ordering, answering my queries and to fitting the door the service was excellent, every member of staff involved was polite, friendly and professional. On the day of fitting the team worked swiftly, effectively and left absolutely no mess. They also went the extra mile and dealt with an additional request regarding the interior of my hall. The door is fabulous quality and looks great, having transformed the exterior of my house and improved the interior hallway. I cannot recommend L&L installations highly enough, they also provide annual servicing on their doors which was an unexpected bonus! If you want a reliable and professional service, great quality and finish of door and clear pricing use L&L.

I want to give my appreciation to the L&L team for completing our job of replacement windows and door. I have to say the whole process was an enjoyable experience for us. From the initial enquiry L&L, the first consultation, followed by timely survey and of course meeting the installation team, what a fantastic team L&L are. With their advice and guidance I had imagined how our new windows would look but the finished product has even surpassed those high expectations. My thanks go to the whole team and the Directors of L&L.

From getting the quotation to getting the windows fitted L & L's customer service was fantastic. David in particular always kept in touch with updates and progress reports and making sure we were happy with what was going on. The installation was smooth and there was no mess, which was an added bonus and in before Christmas which was part of their promise and they kept it. The product, Aluco, is fabulous and fitted on the extension of our old cottage, not in the least intrusive and in line with the old Victorian windows on the original building but with the added bonus of double glazing. Maybe someday in the future we may consider replacing the old windows and we will go back to L & L should we decide on this course of action. Hats off to L & L, great job from start to finish. Still want a stable door but lockdown restrictions have prevented us from visiting the showroom. Someday soon though that will happen.

We needed to replace our front door to improve access for a disabled family member wearing a prosthetic leg. The sales and survey personnel took great care in understanding the criteria to be met and then to select the most appropriate solution. This was followed by a timely installation by two experienced, friendly and professional fitters. A first class service was provided throughout. We are very pleased with L and L installations and would recommend the company to anyone.

Had a new front door and frame installed by L and L. Everyone involved has been very courteous, helpful and professional, from the sales staff to the installation team. The quality of the product is also excellent it just feels so much more 'solid' than the old door. Would not hesitate to recommend, and in fact already have.

L & L have replaced many windows for us over the years. Their work is outstanding in every respect including the fact that they leave the site clean and tidy, check that we are satisfied a few days after the event and regularly inspect the windows for several years to see if they need any adjustment.

We first used L & L Installations to replace windows 27 years ago. They did a fantastic job and nothing was too much trouble to design and then produce perfectly balanced and matched windows for our period home. a few years down the line they undertook the removal of our old front door and replaced it with a window and lovely cotswold stone brickwork. When we extended in 2006 we overruled our builder and insisted that the windows came from L & L as a result! Every installation was checked annually, without fail for 10 years after. We have just had another four large windows replaced by L & L. Standards are just as good as ever - the first visit ensures that you get a quote for exactly what you want; the survey is then undertaken by someone who has been fully briefed and knows exactly what the job entails. The fitting took place over three days; there was lots of communication beforehand about when this would be done, and the guys turned up on time, operated in a Covid-secure manner, left everything neat and tidy each evening by clearing up and hoovering after themselves, and the end product is great. It was not an easy job and we are very pleased with the results. We highly recommend this caring family company, and will use them again - I am now saving for a sash window for the rear of the house!

We live in an old farmhouse and have progressively been been replacing different windows over a number of years using L&L with the Evolution range of windows. Each time we have been entirely satisfied with not only the product but the attention to detail and installation teams. Well done
